This is an interesting comment as we have no way of validating how much money designers are putting into their own algorithms. I started building algorithms on Quantopian 2.5 years ago, using it as a way to teach myself how to code because I come from a finance background and had no coding experience. I now have a portfolio of algorithms that consistently produce alpha (so far). My favorite algorithm does valuations and then buys and holds for long periods of time. I don't actually invest any money into this algorithm but rather use it as a prescreener for my own personal investments. I have a significant amount of 'skin in the game' because of the amount of time I have invested in developing my algorithms in addition to half of my (very little) net worth being allocated based on the suggestions of my algorithm. I wouldn't be surprised if other designers were in the same boat. This is purely anecdotal but I hope it helps.
